Eco-tourism links travel with protected areas, wildlife conservation, local employment, and community income. The figures below cover historical World Bank case studies, mostly from 2005, 2015, and 2019, alongside the U.S. National Park Service’s 2025 visitation release. Because the locations and measurement periods differ, each statistic is labeled by geography and date rather than treated as a single global average.

Protected-area tourism and national economies
The World Bank report Banking on Protected Areas presents protected-area tourism as a measurable part of several national and regional economies. Its figures are case-study results and historical estimates, so they should be read in their stated currency, geography, and year.
In Zambia, the average protected-area tourist spent US$1,100 per trip in 2005. The calculation covered 176,000 tourists. Total protected-area tourism spending in Zambia reached US$194 million in the same year, equivalent to 3.1% of Zambia’s 2005 GDP. The activity also created 19,000 formal jobs. These figures describe the economic footprint of protected-area tourism in Zambia, not a current global eco-tourism average. [World Bank report: Banking on Protected Areas]
Uganda’s tourism exports totaled US$431 million in 2019, measured in 2019 U.S. dollars. Those tourist exports represented 6.3% of the country’s total exports. This national measure is broader than spending inside one protected area, but it helps show the potential scale of nature-related travel within an export economy. [World Bank report: Banking on Protected Areas]
The South Luangwa area in Zambia generated about US$38 million in value added, measured in 2015 U.S. dollars. Tourism there also produced US$19 million in wages and salaries and supported about 3,000 jobs. The three figures describe the same regional case study from different economic perspectives: total value added, employee compensation, and employment. [World Bank report: Banking on Protected Areas]
The Galapagos case study separates island and national effects. Tourism generated US$62.9 million on the islands in 2005 U.S. dollars, while tourism in Ecuador generated US$113.9 million in the same study. A US$1,000 increase in foreign tourist expenditure raised island income by US$218. A US$1,000 increase in domestic tourist expenditure raised total island income by US$429. These are modeled income effects for the case study, not claims that every visitor dollar has the same result elsewhere. [World Bank report: Banking on Protected Areas]
| Location and period | Reported tourism measure |
|---|---|
| Zambia protected areas, 2005 | US$194 million total spending |
| South Luangwa, 2015 dollars | About US$38 million value added |
| Galapagos islands, 2005 dollars | US$62.9 million generated |
| Ecuador, same Galapagos study | US$113.9 million generated |
| Uganda, 2019 dollars | US$431 million tourist exports |
Kenya’s case study estimated that every dollar invested in conservation and wildlife tourism could generate benefits between 3 and 20 times higher. The wide range reflects a potential return estimate rather than a guaranteed result. [World Bank report: Banking on Protected Areas]
Jobs and household income
Nature-based travel can support employment directly at lodges, parks, transport businesses, and visitor services, while also affecting jobs through wider local spending. The reported job figures vary substantially by place and by whether secondary effects are included.
In Fiji’s Mamanuca Islands, tourism created 8,304 jobs through direct and indirect channels. Those jobs employed 13% of the local population in the Mamanucas and adjoining coastal areas. In Zambia, protected-area tourism generated jobs for 14% of the working-age population around Lower Zambezi and 30% of the working-age population around South Luangwa. Around Nepal’s Chitwan National Park, tourism-related jobs were held by 3% of the working-age population. In Brazil’s coastal region, tourism-related jobs were held by 12% of the working-age population. [World Bank report: Banking on Protected Areas]
The scale of these percentages should not be compared without noting the different denominators and geographic boundaries. “Local population,” “working-age population,” and a named protected-area region are not interchangeable measures. They are useful for showing local economic dependence, not for ranking destinations by visitor quality or sustainability.
The U.S. National Park Service figures provide a separate national example for 2019. Visitor spending directly supported 204,800 jobs, US$6.3 billion in labor income, US$10.7 billion in value added, and US$17.2 billion in economic output. When secondary effects were included, the totals rose to 340,500 jobs, US$14.1 billion in labor income, US$24.3 billion in value added, and US$41.7 billion in national economic output. [World Bank report: Banking on Protected Areas]
The distinction between direct and total effects matters. Direct employment measures activity immediately associated with visitor spending; the larger total figures include secondary effects in the modeled economy. They should not be added together as separate benefits.
Local economic multipliers
Income multipliers estimate how spending circulates through a local economy. The World Bank study reported normalized income multipliers above 1 in all four of its country cases. A multiplier greater than 1 indicates that the modeled income effect exceeded the initial local tourism income under the study’s methodology; it does not mean that visitors created more than one dollar of cash revenue at every business.
The normalized income multiplier was 1.82 for Lower Zambezi, 1.53 for South Luangwa, 1.78 for Chitwan National Park, 1.74 for Abrolhos Marine Park, and 1.83 for Fiji’s Mamanuca Islands. The values are compact indicators, but the surrounding economic conditions differ across Zambia, Nepal, Brazil, and Fiji. [World Bank report: Banking on Protected Areas]
The study also examined whether poor households benefited from tourism income multipliers. In the reported comparison, 83% of poor households around South Luangwa benefited, compared with 56% around Lower Zambezi. This is a distributional measure for those case-study areas, not a statement about all communities near national parks. [World Bank report: Banking on Protected Areas]
The Galapagos estimates illustrate another kind of multiplier effect. Each US$1,000 increase in foreign tourist expenditure was associated with US$218 in additional island income, while each US$1,000 increase in domestic tourist expenditure was associated with US$429 in total island income. The different estimates reinforce why visitor origin and the defined income measure matter when interpreting eco-tourism statistics.
Public investment and conservation returns
The report estimated annual rates of return on government spending for tourism in protected areas. The rate was 16.7% in Lower Zambezi, 28.2% in South Luangwa, 6.2% around Chitwan National Park, and 7.6% around Abrolhos Marine Park. These are case-study estimates of public-spending returns, not interest rates available to travelers or a universal conservation benchmark. [World Bank report: Banking on Protected Areas]
The same research summarized return-on-investment effects above US$6.2 and up to US$28.2 per public dollar invested in protected-area tourist spending. The range is consistent with the reported case differences, but it should not be interpreted as a promise that a new park will reproduce the highest result. [World Bank report: Banking on Protected Areas]
Visitor capacity can affect projected economic impact. Abrolhos Marine Park recorded 8,044 annual visits in the Brazil case study. If the park reached its carrying capacity of 225 visitors per day, its economic impact was estimated at US$11.9 million. The estimate is conditional on reaching the stated capacity, so it is not the same as observed annual impact at 8,044 visits. [World Bank report: Banking on Protected Areas]
The research base included more than 800 household surveys and more than 20 lodge and business surveys across its four-country study. It also collected 226 tourist surveys in Fiji’s Mamanuca Islands. These sample counts describe the study design and help put the estimates in context; they do not establish a worldwide sample of eco-tourists. [World Bank report: Banking on Protected Areas]
Tourism pressure and community costs
Economic benefits do not remove the costs that protected-area communities can experience. The World Bank case studies reported wildlife-related crop losses around three parks in 2019. Wildlife caused crop losses affecting 14% of crops around Lower Zambezi National Park, 11% around South Luangwa National Park, and 9% around Chitwan National Park.
The corresponding estimated crop-loss costs were US$1.8 million around Lower Zambezi, US$1.2 million around South Luangwa, and US$2.9 million around Chitwan. These costs are local case-study estimates and should be considered alongside tourism income rather than ignored when assessing conservation outcomes. [World Bank report: Banking on Protected Areas]
The figures also show why “more visitors” is not a complete sustainability measure. The Abrolhos capacity estimate, the crop-loss figures, and the household-benefit comparison all point to the need to distinguish visitor volume from local economic distribution and community costs. No single number here measures the full environmental or social performance of a destination.
Visitor scale in parks and protected areas
The supplied Zambia comparison described 3.2 million visitors associated with protected areas and tourism, versus 20.4 million visitors after nine years of growth in parks and heritage tourism. The report’s legacy summary also recorded more than 320 million visitors per year at U.S. parks and heritage sites. Those U.S. visitors spent an estimated US$21 billion in local gateway regions, supporting more than 340,500 jobs and generating US$41.7 billion in U.S. economic output. Because the summary is historical and its comparison combines different tourism categories, these figures should not be read as a current global trend. [World Bank report: Banking on Protected Areas]
The latest time period in this article comes from the U.S. National Park Service’s 2025 visitation statistics release. Across 406 parks reporting visitation figures, the NPS recorded 323,014,305 recreation visits. Those visits represented 1,386,749,187 recreation visitor hours, and the agency recorded 13,016,577 overnight stays. These are 2025 NPS measures for the United States, not a worldwide eco-tourism total and not a direct measure of protected-area spending. [NPS visitation statistics release]
For independent travelers, the practical lesson from these statistics is to read the unit before comparing destinations: a visit, visitor hour, overnight stay, job, household share, local income multiplier, and national export total each answer a different question. The geography and measurement period are equally important. Zambia’s 2005 spending estimate, Uganda’s 2019 tourist exports, the historical U.S. economic model, and the NPS’s 2025 visitation count describe distinct parts of the relationship between travel and protected areas.
